Netherlands, assignor to U. S. Slicing Machine Company, Inc., a corporation of Indiana Application August 4, 1947, Serial No. 7 66,026 In the-Netherlands September 1.2,v 1942 p Section-1, Public Law 690, Agst 1946 l Patent expires September 1,2, 1962 L j This invention relates in general to slicing ma.- chines of the type having a reciprocable carriage that embodies two components that are interconnected to form a rigid structural unit, the upper component being the substance carrier and the lower'component being afsupport which is reciprocable along oneI or more guides on' vthemachine frame, beingconstrained by said guide or guides to longitudinal movement; that is to say, the support `component is constrained against movement relative to the slicing plane.

The present invention embodies a machine of the type wherein the carrier component and the longitudinally guided component of the recipro.- eating carriage are interconnected to form a rigid structural unit by male and female joint members which take the vforces due to the weight of the carrier component and the substance thereon, the reciprocating motion of the support component and the slicing action of the knife and which are disconnectible by the act of lifting the carrier component.

The present invention also embodies a slicing machine of the type stated wherein the carrier component and the longitudinally guided support component of the reciprocating carriage are interconnected to .form a rigid structural unit by a pin in one component fitting into a hole in the other component, with or without another pin in one component fitting into a hole or other opening in the other component, said pin or pins being vertical or substantially vertical so that the carrier component can be detached by lifting it.

Therefore the arrangement is such that the two components of the reciprocating carriage are securely and rigidly interconnected in the operation of the machine and nevertheless the carrier component can be removed from the longitudinally guided support component simply by a lifting action.

In the drawing and in the present exempliiication of the invention Figure l is a sectional View of the machine as Aviewed from the front thereof, i. e. the end where the operator stands.

Figure 2 is a corresponding sectional plan, the upper component of the carriage being removed to show the joint members on the lower component.

Figure 3 is an enlarged detail sectional View on line 3--3, Figure 2.

The machine shown embodies the usual rotary knife I, which is journaled in a knife bracket 2, being set at a slight inclination to the slic lng plane. The knife is driven by a motor 3, prefsolaims. (ci. 14e- 162) Y' erably of the electric type. Thel'thickness of the slice cut from the substance by the knife isregulated by a gage plate 4, which is adjustable in'any manner well known in this art, by a regulator knob orhandle 5, to give any selected slice thickness. The gage platerd is supported by one or more guide rodsv', which extend at -anvelevation into one or more guide' bearings in the base l, of the machine frame. The slicereceiver of the machine consists ,-of a platform 8, forming an extension of the base.

The reciprocable carriage includes at its upper component a substance carrier I0. The guides for the carriage include an upper round bar VI I, secured at its ends lto the base l. Y

The lower guide means includes a `roller I2, which runs betweentwo opposed `tracks I3, and I4, provided in the base 1. The lroller I2, is journaled on the lower component of the reciprocating carriage, said lower component taking the form of a block like support I5, whichv is slidable on the bar II. l., V i

l As usual in suchmachines, amaskvv plate I6, is mounted in front of the knife, this mask plate being formed at the foot with an outwardly'projecting horizontal flange Il, which assures a po-` sitionnflush with a similar flange I8', on thegage plate 4. The mask plate is pivotally supported at one side, the pivot being designated by the numeral I9, the arrangement being such that the mask plate may be swung aside from the knife to facilitate cleaning, a knife guard 24, being also provided.

In the form of the invention shown, the support I5, is provided with two upright pins 2U and 2 I, as a means whereby the carrier I0, is detachably connected to it. These pins are made to t precisely into a similarly spaced pair of holes 22 provided in the underside of the carrier I0. As shown, the hole 22 constitutes a bore through a long neck 25, which projects vertically downwards from the carrier I0. The bore has a small sized upper portion and an enlarged lower portion which leads to the mouth of the hole. The pin 20 is comparatively long, its length being preferably several times as great as its diameter, and the size of the pin is such that it ts neatly the small sized top portion of the hole 22. The mouth of the hole engages and is accurately centered by the conical base 2B, in the working position of the carrier IU, on the support I5.

The other hole provided in the underside of the carrier IU may be a simple hole to receive and fit the pin 2l. These parts serve mainly to hold the carrier I0, against turning about the axis of 3 the pin 20, with which the neck 25 may be regarded as the main joining means in the form shown.

The arrangement issuch that .the joint inembers arqwell adaptedv to maintain a secure and rigid connection between the carrier I0, and the support l5', in the operation of the machine, ther Y joint thus taking the forces due to the weight of the carrier and the substance upon it, the -recipro eating motion of the support and the slicing action of the knife. Nevertheless rin order to disconnect the carrier l0, it is only necessary to raise or lift it from the support.

' While the preferred form of' the invention is herein shown and described, it is to be Yundervstood that Various changes may be made 4in the Y details of construction and in the combination Y the carriage, Vsaid meansembodying a pin on said carriage andprovided with a conicalbase portion andra body portion of substantial length and of ar diameter less than'the diameter of saidbase portion,fsaid rcarrier having a recess to receive said pin, said recess beingpprovided'with a. por tion tot said pin, an enlarged portion which receives and fits said conical base portion of the pin, and an additional pin-and-socket connection between said carrier and said carriage spaced from said pin having the conical base and recess connection to prevent pivoting of the carrier rela-tive'to the carriage for maintaining the carrier against turning with respect to the carriage.
